I just changed the battery in my 1990 bmw Now my car won't start or make any effort to start. I think I hooked the battery up wrong. I do not know what the small black and red wires connected to the battery are but I think I put them back on wrong. I like a dumb ass did not take pictures of the cars battery before changing it. Could anyone tell me how these wires are supposed to be hooked up or possibly take a picture of their battery?
